In voice and video over IP (VoIP/Video) communications, jitter refers to the variation in packet arrival time, causing delays or inconsistencies in the delivery of audio and video data. Two key characteristics of jitter are:
1. Variation in Latency:
Jitter is essentially the inconsistency in latency, meaning the time it takes for data packets to travel across the network is not consistent. Some packets may arrive with delays, while others may arrive on time, leading to a fluctuating and unpredictable flow of data.
2. Impact on Real-time Communication:
Jitter significantly impacts real-time applications like VoIP and video calls. High levels of jitter can lead to choppy audio, video lag, and even dropped packets, resulting in a poor user experience.
